How Do I Remove Old Wallpaper?

How do I remove old wallpaper?

To remove old wallpaper, start by scoring the paper to allow a remover solution to penetrate. Apply the solution generously, let it soak, and then peel or scrape away the wallpaper. For stubborn areas, repeat the process or use a steamer.

Removing old wallpaper can seem daunting, but with the right approach, you can achieve a clean surface for your next decorating project. The key is patience and the correct tools. Before you begin, protect your floors and any surrounding furniture with drop cloths or plastic sheeting. Turn off the electricity to the room at the breaker box to avoid any accidents with electrical outlets or switches.

The first step involves scoring the wallpaper. This creates tiny holes that allow your chosen removal solution to penetrate the paper and reach the adhesive. You can use a specialized wallpaper scoring tool, a utility knife, or even coarse sandpaper. Be firm but avoid pressing too hard, which could damage the drywall underneath. Focus on scoring the entire surface of the wallpaper, especially in areas where seams are visible.

What solutions can I use to remove wallpaper?

Once scored, you need a solution to dissolve the wallpaper adhesive. For most standard vinyl or paper-backed wallpapers, a mixture of hot water and dish soap or a commercial wallpaper remover solution works well. Mix the solution according to the product’s instructions or use about two tablespoons of dish soap per gallon of hot water. You can also add a small amount of white vinegar, which can help break down the glue.

Apply the solution liberally using a sponge, spray bottle, or garden sprayer. Ensure the entire surface is saturated. Allow the solution to soak into the wallpaper for at least 15-20 minutes. The goal is to let the moisture penetrate the paper and loosen the adhesive. You should see the wallpaper begin to bubble or soften. If it starts to dry out, reapply the solution.

How do I physically remove the wallpaper?

After the solution has had time to work, you can begin the physical removal process. Start at a seam or a corner and try to peel the wallpaper away. A putty knife or a plastic scraper is ideal for lifting edges and gently scraping off loosened paper. Work in small sections, always pushing the scraper away from you to avoid gouging the drywall. If the wallpaper comes off in large sheets, you’re doing great. If it’s coming off in small strips, don’t worry; just keep scraping.

What if the wallpaper is stubborn or painted over?

For particularly stubborn wallpaper, especially if it’s vinyl-coated or has multiple layers, you might need a wallpaper steamer. Rent or purchase a steamer and follow the manufacturer’s instructions. Hold the steamer plate against the wall for about 30 seconds to a minute, allowing the steam to penetrate. Work in small sections, as the steam will loosen the adhesive quickly. Be careful not to over-steam any one area, as excessive moisture can damage drywall.

If the wallpaper has been painted over, scoring and applying a solution may not be enough. The paint acts as a barrier. In this case, a steamer is usually the most effective method. You might also need to score more aggressively. Some people find success with a mixture of fabric softener and hot water, applied and left to soak, but a steamer is generally more reliable for painted-over wallpaper.

How do I clean the walls after removing wallpaper?

Once all the wallpaper is removed, you’ll likely have residual adhesive on the walls. This needs to be cleaned thoroughly before you can paint or re-wallpaper. Use a sponge and a solution of warm water and a small amount of TSP (trisodium phosphate) substitute or a dedicated adhesive remover. Scrub the walls to remove any sticky residue. Rinse the walls thoroughly with clean water and allow them to dry completely. Inspect the walls for any remaining glue or paper bits and scrape them away as needed.

What tools and supplies do I need for wallpaper removal?

Gathering the right tools before you start will make the job much smoother. You’ll need:

– Drop cloths or plastic sheeting to protect floors and furniture

– Painter’s tape to secure drop cloths and protect trim

– Scoring tool (e.g., wallpaper scorer, utility knife, sandpaper)

– Spray bottle, sponge, or garden sprayer for solution

– Wallpaper remover solution (commercial or DIY)

– Putty knife or plastic scraper

– Bucket for water and solution

– Ladder or step stool for high areas

– Gloves to protect your hands

– Safety glasses to protect your eyes

– Wallpaper steamer (optional, for stubborn wallpaper)

Common Mistakes During Wallpaper Removal

Step/Tool Typical Mistake Consequence
Scoring the wallpaper Not scoring enough, or scoring too deep Solution won’t penetrate, or drywall is damaged
Applying removal solution Not letting the solution soak long enough Wallpaper adhesive remains difficult to remove
Scraping wallpaper Using a metal scraper aggressively Gouging or tearing the drywall surface
Using a steamer Holding the steamer in one spot for too long Excessive moisture can damage drywall, leading to mold or structural issues
Cleaning walls Not removing all adhesive residue New paint or wallpaper won’t adhere properly, leading to peeling

FAQ

Can I just paint over old wallpaper?

While technically possible, painting over old wallpaper is generally not recommended. The seams may show through, the paper could bubble or peel over time, and it makes future removal much more difficult. It’s best to remove the wallpaper first for a smooth, professional finish.

How long does it take to remove wallpaper?

The time it takes can vary significantly based on the type of wallpaper, the adhesive used, and the age of the paper. A small room with easy-to-remove paper might take a few hours, while a larger room with stubborn, multiple layers could take a full day or even longer.

What is the best way to remove wallpaper glue residue?

The most effective way to remove wallpaper glue residue is to use a solution of warm water and a TSP (trisodium phosphate) substitute or a commercial adhesive remover. Scrub the walls with a sponge or cloth, rinse thoroughly with clean water, and allow the walls to dry completely before proceeding.

Should I use a steamer or a chemical remover?

A steamer is generally more effective for stubborn, old, or painted-over wallpaper, as the heat and moisture loosen the adhesive efficiently. Chemical removers are often sufficient for standard, unpainted wallpaper and can be less messy than steaming, but may require more effort for tough jobs.
